Machining techniques that reduce the amplitude of low-speed radial uniformity measurements and their effects on smooth-road vehicle vibrations were investigated. The methods ranged from simple concentric and eccentric truing suited for service work to a servo-controlled tire-wheel assembly measuring and corrective machine installed at an auto assembly plant. These methods produce significant reduction of the measured low-speed radial uniformity. Corresponding vehicle evaluation showed significant reduction of smooth-road shake-a 1 per wheel revolution vibration-but little change of higher order vibrations. The simplicity of eccentric truing, combined with its predictable reduction of shake, provides a service fix for smooth-road shake.
